<p>The invention provides a method and apparatus for radix- beta non-restoring division. The division process occurs in four phases. In a first phase, the input operands are transformed to produce a divisor lying in a designated numerical range. Next, a transitional phase involves generating an initial radix- beta quotient digit from the transformed numerator. An iterative phase of the process generates successive partial remainders according to a recursive method. From the sign and a single radix- beta digit of each of these partial remainders, the process generates a radix- beta quotient digit. Further, a fourth phase, which may run concurrently with the transitional and iterative phases, involves accumulating succesively generated quotient digits to produce a final quotient value.</p> |
